Purpose : The objective of the present study is to review the single-center experience of robotic mitral valve (MV) repair and analyze the clinical outcomes and long-term durability of repaired MV.

Methods : A total of 450 patients who underwent robotic MV repair to treat mitral regurgitation (MR) between 2007 and 2018 in our institution were evaluated. The baseline demographics, operative profile and both perioperative and long-term outcomes including follow-up echocardiographic data were analyzed.

Results : The most common etiology was degenerative (n=398, 88.4%) followed by endocarditis (n=25, 5.6%) and rheumatic (n=23, 5.1%). Surgical ablation for atrial fibrillation (n=100, 22.2%) and tricuspid annuloplasty (n=65, 14.4%) were the most frequent concomitant procedures. MV was successfully repaired with no or mild residual MR in 438 (97.3%) patients. There was no early mortality occurred. The early complication included: low cardiac output syndrome (n=2, 0.4%), stroke (n=5, 1.1%) and MV reoperation (n=2, 0.4%). On follow-up, (median 38.7 months, range 18.6-75.7 months), death and MV reoperation occurred in 9 (2.0%) and 7 (1.6%) patients, respectively. Major event-free survival at 10- years was 79.4±2.9%, Follow-up echocardiographic data (>6 months after MV repair) were obtained in 421 (93.6%) patients. During follow-up, 55 (12.2%) patients demonstrated more than mild MR and freedom from more than mild MR at 10-years was 82.0±2.2%, respectively.

Conclusion : Robotic MV repair is a safe and efficacious procedure to treat MR with excellent short-and long-term outcomes. Robotic-assisted surgical approach was applicable to manage various etiologies of MV with concomitant cardiac surgeries. Furthermore, the long-term durability of MV was favorable.
